Damp Proof Injection Fluid
Siliconate K is a BBA Approved damp proof injection fluid concentrate. Once diluted with water the liquid is introduced in to predrilled holes by either transfusion or low pressure injection to form a chemical damp proof course in masonry walls.
The concentrate is supplied in a 3.6 litre bottle and should be diluted in a controlled environment and at a 1:6.ratio to make 25 litres of diluted damp proof liquid.
Injection holes should be drilled either horizontally in to the mortar beds or angled downwards at an angle of 30°to 45°terminating in a mortar bed at the level of the required damp proof course. Injection of the solution should be carried out at a pressure not exceeding 300kPa. In saturated walls, lower pressures over longer periods of time are likely to be more successful
Inject damp proof fluid at the rate of 3 litres per metre run of 230mm thickness wall. Pro-rata injection rates for the treatment of rising damp in solid walls of different thicknesses.
